Abstract
• Dyes with improved biodegradability for coloring textiles comprise a chromophore bound to one or more mols. of a mono- or disaccharide. A typical dye I was manufd. by stirring 1,2:3,4-di-O-isopropylidenegalactose 6-succinate monoester 3, 2-[ethyl[4-(phenylazo)phenyl]amino]ethanol 2.69, N'-[3-(dimethylamino)propyl]-N-ethylcarbodiimide 1.92, dimethylaminopyridine 0.0305 g in THF 16 h.File in questo prodotto:
